NNCONDUCTNG SECTGNAL VIALL.

Application lcd July 18, 1925.

The invention relates to non-conducting sectional wall, as described inthe present specification and illustrated in the accompanying' drawingsthat form part of the same. V

rThe invention consists essentially of the novel features ofconstruction pointed out in the elaimfor novelty following a descriptioncontaining an explanation in detail an acceptable form of the invention,

The objects of the invention are to protect the contents of chambers andpassages, ccntaining flowing or quiet liquid from frost or otherclimatic conditions; specilically to protect water passages fron'ifrost, such as the mains from sprinkler or other water supply tanks setat an elevationV in exposed places; to facilitate the installation ofprotective casings for various uses; to furnish a construction that willlend itself to the fortilication of enclosed substances and materiallylessen the possibilities of temperature disarrangements; to produce afrost wall at a reasonable cost and of indestructible material andthereby avoid damage to life and property; and generally to provide adurable, efficient and economical means for enclosing chambers andpassages.

In the drawings, Figure 1 is an elevation of a water tank showing` oneapplication of this invention.

Figure 2 is an enlarged cross sectional view of the invention showingthe stand pipe and protecting wall.

Figure 3 is an elevation of awater tank. showing another application ofthe invention` Figure 4 is a detail of the joint between the tank andthe protecting wall.

Figure 5 is a detail disclosing the spacing block.

Figure 6 is a plan of the wall sections, bound together in a double wallarrangement.

Like numerals of reference indicate corresponding parts in the variousfigures.

In this invention materials that are very well known in coverings forpipes, walls and other installations are used, in fact the corrugatedfeature to effect air spaces is common to boxes, wrappers of all kinds,pipes, coverings and to wall structures.

It will be seen in the description of this invention that not only newcombinations of parts are set forth but new structural features arepointed out quite novel in the art.

Serial Ho. 44.555.

Referring to the drawings, thc numeral 10 indicates a stand pipe of awater tank 11 and the numeral l2 the frost proof wall, while 13indicates the dead air space, forming an annular sealed chamber aroundthe stand pipe 10.

The wall 1Q is iixedly secured and sealed to the bottom of the tank atits upper end and to the ground, the roof of a building or other base atthe lower end, so as to form the sealed annular chamber 13 aforesaid.

rEhe wall 12 is formed of the sections 14 arenal in cross section andformed in lengths of the desired height and breadth for the purposes oftheir use.

rl"he wall is of a composite nature being made of asbestos paper,rooting or lining felt and a ceinentitious substance adapted to stillenthe structure. rlhe several sections are coated with a bituminous andasbestos lire and water proofing substance and are joined together by anasbestos cement, which is applied a motor so as to fill in and tocompletely cover the joints.

The asbestos paper is arranged in alternate layers of corrugated sheets15 and plain sheets 16 and 17.

The inner and outer walls of each section are covered with the roofingor lining felt 18, as also are the ends at 19, the end piecesoverlapping the outer and inner coverings, thus completelyY enclosingthe asbestos paper which is previously treated with a cementitioussubstance for stilfening purposes, this substance not being speciliedthough it will in most cases be of a silicious nature.

The sections are sealed and form individual parts to a wall and theasbestos cement 22 is introduced between the end and side walls of theseparts and spread over the joints in the same manner as mortar in orderthat the chamber surrounding the water pipe or other enclosure to beprotected may be effectively closed in, and further the strips 23 areadded across the joints and the cement trowelled thereover at the edges.

In erecting the wall the sections are securely bound by the hoops 24fastened by the clamp 25, by means of which the sections are broughtinto closer relationship in order to insure air tight joints at thecement joinings.

The completed wall is preferably sealed at the tank bottom by filling ofsuitable fire and waterproofing material 26 of an asbestos andbituminous nature, this material being' introduced and packed above thetop of the Wall and against the bracket 27 securing the pipe to thetank.

The circular sheet 28 eneircles the wall and is fastened thereto andextends across to the angle bar 29 thus completely enclosing thefillingand packing 26, this sheet, being made oft rooting felt or othersuitable fire and Water prooi' material.

The spacing blocks 30 maintain the Wall at an even distance from thestand pipe and are preferably placed at the joints et the Wall sections.

The rooting or lining' felt forms the outer easing of the section andthe ends are preferably separate pieces. Naturally this casing` may beof several thicknesses, the outer layer being coated on all sides withan asphaltic and asbestic compound to withstand the raya-ges of theWeather and generally to endure under severe climatic conditions.

It Will be seen that the sections when joined together as described forma. tubular casing Which can readily be closed at the ends and therebyform the annular dead air chamber already mentioned.

' There are many other uses 1for this partieular kind of Wall or casing7Where the application thereol will necessitate quite different details,though the actual structural teatures outside of the shape Will remainsubstantially the same.

One of the many advantages oit this Wall is its great strength andrigidity which combined with its lightness makes it a desirableprotection, especially Where a considerable weight is objectionable.Besides for shipping purposes it is of great importance to reduce theWeight and yet be assured of the durability.

Vihat I claim is A non-conducting sectional Wall, comprising frost proofeasings adapted to encircle the stand pipe of a Water tank and form adead air space therearound, a filling forming a fire and Water proofpacking at the top of said wall and under said tank and a circular sheetot proof material encircling said wall and enclosingr said filling andsecured to the wall and to an angle bar rigid with the bottom oit thetank.
